Door sill for rail car e.g. streetcar, has one set of clamping surfaces maintaining strip against another set of clamping surfaces of support, such that friction force is established between strip and support

摘要

The sill has a support (22) connected to a rail car beam (16) and a strip (24) retained by the support. The strip is moved between a normal position and a retracted position with respect to the support. Clamping surfaces (30A, 30B) of the strip maintain the strip against the clamping surfaces of the support, such that friction force is established between the strip and the support.
